“…However, because of the high-power operations of MPDTs, the plasma density and heavy particle temperature inside the discharge chamber are high (typically ~n T 10 m , 0.5 eV 0 20 3 i [11]), which makes the electric probe diagnosis impossible for the plasma inside the discharge chamber. The spectral diagnosis is influenced by the plasma in the plume region [12], so it is also difficult to diagnose the plasma inside the thruster. The microwave interferometer diagnosis requires the destruction of the thruster structure and it may produce high testing cost [7].…”

In this work, a zero-dimensional plasma model for self-field magnetoplasmadynamic thrusters (SF-MPDTs) is proposed, which is based on the ion-number balance equation and energy balance equation, and can calculate the average electron temperature and the average ion temperature inside the discharge chamber conveniently. At the same time, the model can also predict the thruster performance, and the thruster performance predicted by the model is compared with experimental results, which proved the reliability of the model.
